Title: Magnetic recording medium
Inventor: KONO KENJI
IPC: G11B5/712
Filed: 1989-04-12
Abstract: PURPOSE:To obtain constant dispersibility and adhesion property of different types of magnetic powder for one binder by treating the magnetic powder with a silane coupling agent. CONSTITUTION:Various kinds of magnetic powder are treated with one kind of silane coupling agent. Such a coupling agent is most preferable that contains hydroxy groups as the functional groups as it gives good dispersibility of the powder and durability of the recording medium. For example, magnetic powder flocculates with poore dispersibility when a silane coupling agent having mercapt group is used, while this problem is avoided by treating the magnetic powder with a silane coupling agent such as hydroxy propyltrimethoxy silane. Thereby, various kinds of powder can be used without causing problems of surface state of the medium, and qualities of the medium is stable.

Abstract: PURPOSE:To obtain damping devices also operating stably when constraint by turning a thyristor, which is connected to the node of the series circuits of the two damping devices connected in parallel with a DC motor and one end of a power supply at the AC side, OFF at time earlier than a thyristor connected to the other end. CONSTITUTION:When a forward-direction command signal is at OFF at time t1, the output of a gate switching device 18 is at OFF, the output of a forward-direction gate signal amplifier 20 is at OFF at t1 and the input of forward-direction timers 25, 26 is also at OFF. Forward-direction gate amplifiers 19, 21 output gate signals during the time when the timers 25, 26 count, the timers 25, 26 time up at time t2 after a period corresponding to the half period of the power supply 3, and the output of the amplifiers  19, 21 is at OFF. Consequently, the thyristors 1V, 1Y are at OFF through the application of inverse voltage at time t3, and the thyristors 1U, 1X, 1W, 1Z are at OFF through the application of inverse voltage at time t4. Accordingly, even when the DC motor 4 is constrained, the electromagnetic energy of a DC reactor 5 flows through the damping devices 6, 7 through said operation, and does not flow through the thyristors 1V, 1Y.
